the most recent one i read was ‘ I Reincarnated as the Little Sister of a Death Game Manga's Murder Mastermind and Failed’ the other ones are tamer shoujos called ‘miniamaru kareshi’ and ‘hananoi kun to koi na yamai’ !! i don’t really read yandere but i’ll tag someone under my tweet and my girl is the biggest yandere fan and she might recommend a few if you want
